You can also configure IP filtering on the VMG for secure Internet access. When the IP filter is on, all
incoming traffic from the Internet to your network is blocked by default unless it is initiated from your
network. This means that probes from the outside to your network are not allowed, but you can safely
browse the Internet and download files.
Only use firmware for your VMG’s specific model. Refer to the label on
the bottom of your VMG.
1.1.1.1 Ethernet WAN
If you prefer not to use a DSL line and you have another broadband modem or router (such as ADSL)
available, you can use the Ethernet WAN port and then connect it to the broadband modem or router.
This way, you can access the Internet via an Ethernet connection and still use the QoS, Firewall and
parental control functions on the VMG.

1.1.2 Wireless Access
The VMG is a wireless Access Point (AP) for IEEE 802.11b/g/n/a/ac wireless clients, such as notebook
computers, iPads, smartphones, etc. These devices can connect to the VMG to access network
resources and the Internet.
Your VMG supports Wi-Fi Protected Setup (WPS), which allows you to quickly set up a wireless network
with strong security.
You can configure your wireless network using the built-in Web Configurator.
